| Abstract: | In this paper, an approximate dynamic substructure approach incorporated with the applying of the dynamic infinite element developed in Ref. [2] is proposed to evaluate the dynamic impedance of arch dam canyon cut. The numerical results show that the combination of this approximate method and the dynamic infinite element can effectively model the complexity of geometry and properties of the dam canyon field, whereas efficiency and accuracy of computation are good. |
